The CWS is an amazingly effective component and I've yet to see it cause the first problem in function. I now also "automatically" stick the heaviest weight in the unit (the carbide) and also have yet to see a rifle that didn't work with thataway. -- G. Zediker, 2004 MY TAKE... by Glen Zediker author, The Competitive AR15 David Tubb has been sending a few new things "our" way, and here's one that's too simple and too good to believe. His "CWS" which stands for "carrier weight system" is a drop in part for any AR15 or AR-10/SR-25. It delays the unlocking of the bolt, which gives pressures some time to head in the right direction (which is not toward the case head). The result is that the ammunition in your AR15 doesn't produce any less pressure, but it sho "takes" more. What it is The CWS unit is a tapered steel cylinder with a flange on one end. The part slips into the back of a bolt carrier and stops against the flange. When installed, the whole thing is trapped by the buffer and bolt carrier. Can't come loose. The CWS housing is hollow to accept one of two available weight inserts, a stainless steel and a tungsten carbide. The CWS part alone weighs about one and a half ounces. The stainless insert weighs about that much again, and the carbide is, by itself, about two and a half ounces. That's a potential for adding quite a lot of weight. What it does The CWS delays bolt unlocking. It increases the moment of inertia since it adds weight to the carrier. It doesn't reduce pressure, but that's the effect on the cartridge case and primer. There has been a notable difference in the condition of my cases fired with stuffed loads. The other thing it does is shorten the distance between bolt and bolt stop at full recoil positions. This happens simply because there is an 0.080 thick flange on the CWS. Reducing carrier overrun shortens the return of the bolt into and against the stop. This hasn't really been much problem with AR15s, but broken bolt stops are commonplace on the AR-10 and SR-25. Despite the extra weight the carrier is packing, the run back being shorter makes more positive difference. What it did It's hard to make too much of a claim on the part since, one, I've only used it in a couple of rifles, and, two, I'm not "representing" the product officially. But. I think it's way safe to see that anyone will notice a difference in the behavior of the rifle and in the condition of the spent cases. I can't say that CWS is going to stop most primer launching and primer piercing problems (bolt and firing pin have a whopping lot to do with that, as in "almost everything") but it sho did in my case. I think this part is of perhaps most benefit, which is to say may provide more noticeable improvements, in a Colt® equipped with the receiver block. The block, of course, means that only a Colt® bolt carrier can be used, and that is the lightest carrier out there. The CWS is the only way to increase a Colt® to "heavy carrier" status. What else It's easy enough to install, but the only glitch is that the upper and lower receivers have to be separated at both ends (remove front and rear takedown pins) to get it situated. Again, the flange makes it improbable (didn't say "impossible") to hinge the rear receiver off the front pin and close the units in normal fashion. Not a big deal, but have to keep the screwdrivers handy for a Colt®. Other rifles with front and rear push pins are easy. It's worth the trouble. I won't again fire a Colt® competition Service Rifle without mine. I'm pretty elated about this part. It literally "saved" a rifle for me, or at least got it back in favored status. The Colt® I installed CWS in never would get to speed without serious symptoms, now it's a glutton for punishment. See note at end. Without CWS at 23.0gr H4895 and Sierra 80. x With CWS at 25.0gr H4895 and Sierra 80. Folks, this is NOT a recommended load. Even though the case held together and the primer did too, just look at the extractor marks and ejector imprint on this po head. Don't use this load. Just know what it means to this article and my evaluation of CWS. Very important note -- In this example I am in no way insinuating that CWS will or should allow anyone to increase a powder charge in this amount, or even close to it. Point is that overt symptoms of excessive pressure were abated in this seriously over pressure load. Don't take this any other way! x What's Else Big deal is that I didn't yet do the big deal, which is the carbide weight. My results came from the stainless steel insert. The carbide adds another third. More to come, rest assured. I have no doubt that the carbide will "work" in this Service Rifle.
